hash_hmac的Groovy替代方案

import javax.crypto.Mac
import javax.crypto.spec.SecretKeySpec

def calculateHmac(String algorithm, String key, String message) {
    SecretKeySpec secretKeySpec = new SecretKeySpec(key.getBytes(), algorithm)
    Mac mac = Mac.getInstance(algorithm)
    mac.init(secretKeySpec)
    byte[] hmacBytes = mac.doFinal(message.getBytes())
    return hmacBytes
}

def algorithm = "HmacSHA256"
def key = "your_secret_key"
def message = "your_message"

def hmac = calculateHmac(algorithm, key, message)
println(hmac)
